Sgt. Slaughter was also made into a G.I. Joeaction figure. He was most likely a Marine Corps drill instructor as his filecard for G.I. Joe said his birthplace was Parris Island, SC and his first words are Semper Fi and they called him a jarhead. I remember one figure only being available only by mail. You could also buy the Sgt. Slaughter's Triple-T tank at the store. He was the first celebrity immortalized by Hasbro. He voiced his own character and did some promo/intro work for some of the cartoons.
